A perfect mixing matrix model for ball mills -
2001-10-1 A comminution model is developed for ball mills using the principles of perfect mixing. T-lines are developed from data arising from single particle breakage tests using a laser monitored, twin pendulum breakage device. A t 1.4 parameter is developed that produces a family t-lines which can be modeled using linear equations.

Application of perfect mixing model for simulation of ...
2021-6-16 perfect mixing model. In a perfect mixing ball mill, the feed entering the mill would be distributed along the mill, thus being subjected to the probability for breakage. A similar situation was encountered in a VRM, where the feed that had fallen on the grinding table was being subjected to the breakage process by the rollers,

A specific energy-based ball mill model: From batch ...
2016-2-1 Thus the default breakage appearance function in the existing perfect mixing ball mill model is replaced by the ore-specific breakage characteristic parameters. A model to describe size reduction in a batch grinding ball mill was developed. This model is based on the mass-size balance, or mass conservation, which is expressed by Eq. (1).
